Shrink rap: A beginner’s guide to Koro in females
In a previous blog, I examined Koro (the so-called genital retraction syndrome). This is a culture-bound syndromes found primarily in Asian regions (e.g., China, Singapore, Thailand, India). Koro refers to a kind of “genital hysteria” with “terror stricken” individuals (typically male) believing that that their genitals are shriveling, shrinking up, retracting into the abdomen and/or disappearing, and that this ultimately leads to death. Writing in a 1997 issue of the Journal of Psychology and Human Sexuality, Dr. J.T. Cheng noted of Koro that it:
“Is best perceived as a social malady supported by cultural myths which tend to affect young people who are deprived of proper sex information to explain their physical development”.
Koro is rarely described in women but published case studies in the academic literature do exist. All of these female cases report that the affected women reported the shrinking of the vulval labia, nipples, and/or the breasts. The interesting thing about Koro is that all the body parts affected (penis in males; breasts, nipples and labia in women) are those that naturally swell and shrink in response not only in relation to sexual arousal but also in response to temperature and climate changes, depression, anxiety, stress, fear, illness, and/or psychoactive drug ingestion.
Most Koro epidemics while primarily comprising males always appear to involve a small minority of females. For instance, Dr. Robert Bartholomew’s book Exotic Deviance reports the Koro epidemic that occurred in northeast Thailand at the end of 1976 that affected approximately 2,000 people (primarily rural Thai residents in the border provinces of Maha Sarakham, Nakhon Phanom, Nong Khai and Udon Thani). As with most Koro epidemics, the symptoms included the perception of genital shrinkage and impotence among males, whereas females typically reported sexual frigidity, with breast and vulva shrinkage. The origins of the epidemics can vary and include the supernatural. For instance, in a 1986 issue of the journal Curare, Dr. W.G. Jilek described an atmosphere of collective fear of ghosts during a Koro epidemic in Zhanjiang town (Guangdong in China). Those affected believed that ghosts would make the genitals of men and breast of women shrink and disappear into the abdomen and chest. To end the Koro epidemic, the villagers’ drove the ghosts out of their village used drum-beating, bell ringing and bursting of firecrackers.
In 2005, Vivian Dzokoto and Glenn Adams published a paper in Culture, Medicine and Psychiatry examining genital shrinking epidemics in West Africa. More specifically, they examined all media reports of genital shrinking in six West African nations between January 1997 and October 2003 (comprising a total of 56 media reports). Most of the reports were of males but Dzokoto and Adams noted that three Ghanaian news reports included females. All three women reported experiencing shrinking breasts and/or changes to their genitalia. They also noted that:
“One report described a woman whose ‘private parts sealed.’ Another report described a woman who reported that her genital organ (unspecified) was vanishing. Again, it is unclear whether references to sealing and vanishing of female genitalia represent different ways of describing the same experience or represent qualitatively distinct forms of subjective experience.In all reported cases, experience of symptoms tended to be brief and acute. There were no reported cases of recurrence”.
The earliest report of Koro in a female was arguably be in a 1936 book chapter entitled ‘Psychiatry and Neurology in the Tropics’ by Wulfften Palthe. Since then there have been sporadic reports of female Koro in the literature. One of the more notable cases reported was by Kovács and Osváth in a 1998 issue of the journal Psychpathology. This case was unusual because it was a case of genital retraction syndrome in Hungary (although the woman reported was a Korean woman by background).
In a 1982 issue of the Indian Journal of Psychiatry, Dr. D. Dutta and colleagues reported on the (then) recent epidemic of Koro that occurred in four districts of Assam (June 1982 to September, 1982). The 83 cases they reported included 19 females. Interestingly, all the female Koro cases in this particular sample believed it was their breasts that were affected in some way. More specifically, Dr. Dutta and his team reported that:
“9 out of 19 female cases (47.3%) suffered from genital symptoms in form of shrinkage or pull of the breast. Not a single female complained of labial shrinkage. 12 out of 19 cases (69.1%) reported retrosternal pain and other anxiety symptoms subsequently leading to dissociation of varying degree and duration”.
In 1994, Dr. Arabinda Chowdhury (who has written lots of papers on the topic of Koro) published a paper in the journal Transcultural Psychiatry comprising an analysis of 48 cases of female Koro (based on a population of women that claimed to have Koro in an Indian epidemic in the North Bengal region). In females, Dr. Chowdhury noted that “the cardinal symptom is the perception of retraction or shrinkage of nipple or breast mass into the chest cavity or of labia into the abdomen with acute fear of either imminent death or sexual invalidism”. This was the first paper in the world literature to explore the detailed clinical characteristics of Koro in females. Before examining the individual cases, Dr. Chowdhury examined the gender distribution in seven Koro epidemics. The following statistics were reported: Singapore (1969; 469 cases, 15 female), Thailand (1978; 350 cases, 12 female), Indonesia (1978; 13 cases, 2 female), India (1982; 83 cases, 19 female), India (1985; 31 cases, 13 female), India (1988; 405 cases, 48 female) and China (1988; 232 cases, 37 female).
Dr. Chowdhury reported that of the 48 female cases (aged 8 to 54 years), the mean age was nearly 24 years. In relation to Koro, 56% reported retracting nipples (both breasts in all but two cases), 13% reported a flattening of their breasts, 8% reported a retraction in both breasts, 8% reported a pricking sensation in both breasts, 8% reported retraction of the labia, and 5% reported vaginal pain.
It appears that in the same that penis size seems to be a near-universal concern and/or obsession of men, women also share a similar fear, but with different sexual body parts (i.e., vulvas, breasts, and nipples). All of these body parts in males and females (i.e., penis, scrotum, breasts, nipples) are physiologically capable of changing size not only in relation to sexual arousal but also from other non-sexual factors (temperature and climate change, anxiety, depression, stress, fear, illness, and/or psychoactive drug ingestion/intoxication).
One literature review of 84 case reports of Koro (and Koro-like disorders) published in a 2008 issue of the German Journal of Psychiatry by Dr. Petra Garlipp (Hannover Medical School Germany) concluded that there were two unifying features of the case reports cited in the clinical literature. These were (i) the diversity in relation to the clinical picture, the underlying mental disorder, the treatment approach and their classification and nomenclature chosen, and (ii) the symptom of fear.
In response to Dr. Garlipp’s paper, Dr. Arabinda Chowdhury noted that by only using published case studies, female Koro was hardly discussed (because most data about female Koro comes from data collected during Koro epidemics rather than case study interview data). why the review had been so biased towards males. Based on his own research, Dr. Chowdhury wrote that there were at least 146 female Koro case reports from seven epidemics in the years 1969 to 1988. He believed the large number of cases involving women offered many interesting clinical issues in the female expression of Koro, which should have been included in Garlipp’s review. His view was that the differences between male and female Koro in relation to psychodynamics, presentation and associated clinical features of Koro would have made Garlipp’s paper “more interesting”. However, Dr. Chowdhury’s paper didn’t mention what these differences were. Maybe there is not the data to do this. Although it is known that episodes of female Koro can endure for weeks or months, the origin of female anxiety over the absorption of their sex organs is at present unclear.
